WooCommerce Speed & Cloudflare Setup

I run a WordPress site powered by WooCommerce that has become noticeably sluggish. Pages take too long to render, the checkout experience is slow enough to cause drop-offs, and high-resolution product images hesitate before appearing. I need these three pain points fixed and the whole site routed through Cloudflare so future traffic benefits from CDN caching, HTTP/2, and basic DDoS protection.

Here’s what success looks like for me:
• Page load time: consistent sub-2-second rendering on both desktop and mobile (measured with GTmetrix or PageSpeed Insights).
• Checkout process: no perceptible delays from cart update through order confirmation, even during peak hours.
• Product image loading: images should be optimized, served in next-gen formats where possible, and lazy-loaded without sacrificing quality.
• Cloudflare configuration: DNS moved, SSL/TLS set to Full (strict), appropriate page-rule caching, and automatic platform optimization enabled for WordPress.

You’re free to use any proven mix of techniques—object caching, query optimization, image compression, code minification, critical-CSS extraction, and server-side tweaks—as long as existing functionality and design remain intact. Once complete, please provide a brief summary of what was changed and before-and-after speed metrics so I can see the improvement clearly.
